Description

I've sometime had the need to find a string after a separator, lookup
an object based on the result value and then use it to process
something, like:

String after = ObjectHelper.after(key, ":");
if (after != null) {
MyStuff s = cache.get(after)
if (s != null)

{ s.doSomething(exchange) }

}

So I wonder whether it makes sense to add a 'fluent' variant to these
functions to impement such pattern, like:

<T> Optional<T> after(String value, String delimiter,
Function<String, T> function)

The we could do something like:

ObjectHelper.after(key, ":", cache::get).ifPresent(s ->
s.doSomething(exchange));
